Industrial Pipes
Industrial Pipes – Sizes, Weights and Technical Information
An industrial pipe is a hollow cylindrical structure made from metal—mainly carbon steel or stainless steel—used for conveying fluids, gases, or solids in industrial applications. Compared to residential plumbing pipes, industrial pipes are designed to withstand higher working pressures, extreme temperatures, and aggressive chemical environments.
There are two main production methods: seamless industrial pipes and welded industrial pipes. Seamless pipes are produced from solid billets that are pierced and rolled, providing excellent strength and a smooth inner surface. Welded pipes (ERW, LSAW, SSAW) are made by rolling steel sheets and welding the edges together, offering economical production and uniform wall thickness.
For anti-corrosion performance, industrial pipes can be treated with hot-dip galvanizing, resulting in industrial galvanized steel pipes that are ideal for outdoor and corrosive environments.
What is an Industrial Pipe?
Industrial pipes are engineered hollow sections used to transport liquids, gases, steam, or granular materials in demanding industrial environments. They are designed to handle high internal pressure, elevated or cryogenic temperatures, vibration, and corrosive media.
In industrial projects, pipe selection is based on pressure class, design temperature, medium (water, steam, oil, gas, chemicals), and required standards such as ASTM, EN, ASME, or DIN. The correct combination of wall thickness, material grade, and coating ensures long service life and safe operation.
Industrial Pipe Materials and Grades
Different industries require pipes with specific mechanical and chemical properties. For this reason, various industrial pipe material grades are standardized worldwide to ensure compatibility and safety.
Common Material Types
- Carbon steel industrial pipe: Durable and cost-effective; widely used in oil, gas, district heating, and construction industries.
- Stainless steel industrial pipe (304, 316, 321): High corrosion resistance; ideal for chemical plants, food processing lines, and pharmaceutical facilities.
- Galvanized industrial pipe : Hot-dip zinc coated steel pipe suitable for outdoor, water supply, fire protection, and fencing systems.
- Alloy steel industrial pipe: High-temperature and high-pressure resistant; used in power plants, refineries, and boiler systems.
Common Industrial Pipe Standards
Frequently used international standards include:
- ASTM A53, ASTM A106 – Carbon steel pipes for pressure and structural use
- EN 10255, EN 10216 – European industrial and pressure pipe standards
- ASME B36.10, ASME B36.19 – Dimensional standards for carbon and stainless pipes
- DIN 2448, ISO 3183 – German and international pipeline standards
These standards define industrial pipe dimensions, tolerances, chemical composition and mechanical properties to ensure global compatibility and safe operation.

Technical Notes & Calculation
Theoretical weight formula for a hollow cylinder:
W (kg/m) ≈ 0.02466 × (D − t) × t (D, t in millimeters)
Standards used: ASME B36.10M (carbon steel), ASME B36.19M (stainless steel) and related EN / DIN dimensional standards.
Types of Industrial Pipes
1. Industrial Seamless Pipe
Manufactured by piercing solid steel billets, industrial seamless pipes have no weld seam, resulting in high strength and excellent pressure resistance. They are preferred for high-pressure or high-temperature services such as steam lines, oil and gas transmission, and boiler systems.
2. Industrial Welded Pipe
Produced from steel plates or coils that are rolled and welded, industrial welded pipes are economical and suitable for structural and low-to-medium pressure applications. Common variants:
- ERW (Electric Resistance Welded)
- LSAW (Longitudinal Submerged Arc Welded)
- SSAW (Spiral Submerged Arc Welded / Spiral welded)
3. Industrial Galvanized Pipe
Zinc-coated steel pipes with high corrosion resistance, perfect for water networks, fire protection systems, outdoor structures and fencing. Hot-dip galvanized coatings (e.g. Z275, Z350) combine durability with cost-efficiency.
4. Industrial Stainless Steel Pipe
With superior corrosion and heat resistance, stainless industrial pipes are used in chemical plants, pharmaceuticals, food and beverage production, and hygienic process lines where cleanliness and corrosion resistance are critical.
5. Black Steel Industrial Pipe
Uncoated carbon steel pipes, commonly known as black steel industrial pipes, are suitable for gas lines, fire protection systems, compressed air networks, and structural applications.
Industrial Pipe Surface Finishing Options
Surface protection has a direct impact on the service life of industrial steel pipes. Depending on the environment and application, different finishing options are used:
- Galvanized: Hot-dip galvanized coating to enhance corrosion resistance in outdoor and humid environments.
- Painted: Pipes can be painted in black, gray, or brick red using water-based or solvent-based industrial paints.
- Protective oiled: Cold-rolled products are coated with light protective oil during production to minimize rust during storage and transport.
Industrial pipes can be supplied bare, galvanized, painted, or oiled depending on the application and project requirements.
Applications of Industrial Pipes
The versatility of industrial metal pipes allows them to serve almost every major industry. Typical applications include:
- Construction industry: Structural applications, steel frameworks, columns, trusses, and roofing systems.
- Automotive industry: Vehicle parts, chassis components and automotive sub-industry products.
- Machinery manufacturing: Machine frames, hydraulic systems, process equipment and support structures.
- Furniture manufacturing: Metal furniture, shelving, tables, racks and modern architectural designs.
- Agriculture: Greenhouses, irrigation systems, structural frames and support posts.
- Warehouse and storage systems: Shelving, pallet racks, scaffolding and formwork structures.
Process and Utility Applications
- Oil and gas pipelines : Seamless and welded pipes used for crude oil, natural gas, and refined products.
- Water and wastewater systems : Galvanized or lined steel pipes for clean and potable water, fire networks and process water.
- Chemical and petrochemical plants : Stainless and alloy pipes for acid-resistant and high-temperature conveyance.
- Power generation: High-temperature alloy pipes in boilers, steam lines and turbine systems.
- Mining and cement industry: Abrasion-resistant pipes for slurry and bulk material transport.
- HVAC and fire protection systems: ERW pipes with internal and external coating or galvanizing for long service life.
Thanks to their adaptability, industrial pipes can handle liquids, gases, steam and granular materials efficiently across complex industrial networks.
Industrial Pipe Pricing Factors
The industrial pipe price depends on several key parameters that are evaluated for each project:
- Pipe material (carbon steel, stainless steel, alloy steel, galvanized)
- Size (outside diameter, wall thickness and length)
- Production method (seamless or welded – ERW, LSAW, SSAW)
- Standard and specification (ASTM, EN, ISO, API requirements)
- Surface coating type (bare, galvanized, painted, lined)
- Order quantity, packaging type and logistics route
Generally, carbon steel industrial pipes offer the best balance between strength and affordability, while stainless steel and special alloy pipes command higher prices due to their superior corrosion and temperature resistance.

For instance:
Small diameter pipes (DN15–DN50) are used for instrumentation, cooling, or compressed air systems.
Medium sizes (DN80–DN300) serve process and transfer lines.
Large diameters (DN400+) are used in main transmission and industrial water networks.
Schedule 40 and Schedule 80 industrial pipes are the most common, indicating wall thickness and pressure capability. The industrial pipe pressure rating depends on material strength, wall thickness, and operating temperature. Manufacturers often provide industrial pipe dimensions chart, industrial pipe weight chart, and industrial pipe thickness table for engineering calculations.
